[0060] Before explaining the embodiments of the present application in detail, some of the nouns and terms involved in the embodiments of the present application are first explained. The nouns and terms involved in the embodiments of the present application are subject to the following explanations.

[0061] Drive motor controllers are core control components in applications such as electric vehicles and industrial equipment. They precisely regulate the motor's operating state (such as speed, torque, and direction) and achieve efficient energy conversion and management. These power electronics devices convert direct current (DC) from batteries or other power sources into AC power suitable for driving the motor. They also use algorithms and sensors to control motor operating parameters in real time, ensuring efficient and safe system operation.

[0062] Burn-in testing is a testing method that simulates extreme operating conditions or overloads to verify a product's stability and reliability over extended periods of use. Its core purpose is to expose potential defects (such as component failures and software logic anomalies) before a product leaves the factory, preventing early failures from entering the market.

[0063] In the related art, there is a method of using complex physical equipment to age the drive motor controller. The aging process relies on physical load equipment, and the hardware parameters need to be frequently adjusted to adapt to different test requirements. It is difficult to quickly switch between multi-condition test modes, resulting in low efficiency. In addition, the maintenance cost of physical equipment is high. For example, the mechanical expansion and contraction mechanism is prone to wear and tear, and parts need to be replaced regularly. In addition, the related art controls the aging process through a fixed program and cannot dynamically respond to the actual working conditions of the controller (such as sudden voltage fluctuations, sudden temperature changes, etc.). The test results deviate greatly from the actual application. The related art has bottlenecks such as long test cycles, high costs, and poor scenario adaptability, resulting in poor aging efficiency of the drive motor controller, affecting the user experience.

In addition, the present application performs aging simulation processing on the drive motor controller based on the aging simulation parameters to obtain aging results, which can reduce dependence on physical control devices, can flexibly adjust the control aging process, and improve aging efficiency.

[0074] The embodiments of the present application can be applied to the aging scenario of the drive motor controller. The aging method of the embodiments of the present application can be deployed on a terminal with a human-computer interaction interface. The parameters of the drive motor controller can be configured by displaying the main interface on the human-computer interaction interface, and the aging simulation of the drive motor controller can be performed according to the configured parameters to obtain the aging results, and finally the aging results can be displayed on the visualization area.

[0075] One of the above technical solutions has the following advantages or beneficial effects: This embodiment of the present application allows for flexible configuration of the aging process by configuring parameters in the component bar area of ​​the main interface. The configured aging simulation parameters simulate the driver's operating state on the vehicle computer, improving the efficiency of driver aging. Furthermore, this embodiment of the present application also visualizes the aging results in the visualization area of ​​the main interface, allowing for real-time display of aging parameters through the visualization interface, thereby enhancing the user experience.

[0076] In step S101 of some embodiments, please refer to Figure 1 The main interface includes a visualization area and a component bar area. The visualization area is used to display the aging results, and the component bar area is used to configure the aging parameters and run the aging test according to the aging parameters. The component bar area may include a run button, a switch button, a settings button, an exit button, etc. The settings button allows for configuration of aging test parameters, and the switch button allows for user login, account switching, and other operations. In a feasible embodiment, the system can be exited by clicking the exit button, but exiting the system is not allowed during the aging test.

[0077] In some embodiments, in response to the operation instruction on the component bar area, performing parameter configuration processing on the drive motor controller to obtain aging simulation parameters includes the following steps:

[0078] In response to an operation instruction on the component bar area, entering a system parameter setting window;

[0079] Performing an aging device setting process on the drive motor controller based on the system parameter setting window to obtain product parameters;

[0080] Perform test data setting processing on the drive motor controller based on the system parameter setting window to obtain machine model parameters;

[0081] The aging simulation parameters are obtained according to the product parameters and the machine model parameters.

[0082] In an embodiment of the present application, a system parameter setting window is entered by responding to an operation instruction on the component bar area. The operation instruction on the component bar area can be input through a keyboard or mouse, or can be obtained through voice input or other input. In a feasible embodiment, the system parameter setting window can be entered by clicking a setting button in the component bar area with a mouse, or by clicking a setting button in the component bar area through the touch screen function in the human-computer interaction interface. The system parameter setting window can be used to perform aging equipment setting processing on the drive motor controller to obtain product parameters, and the system parameter setting window can also be used to perform test data setting processing on the drive motor controller to obtain model parameters. The system parameter setting window can be in a pop-up form, and system parameter setting windows with different contents can be popped up by clicking different parameter setting buttons. Different parameters can be set through the system parameter setting window, and the setting method can also be used by receiving different operation instructions through the mouse or keyboard to configure the corresponding parameters. The product parameters are used to configure the parameters of the aging equipment corresponding to the drive motor controller, such as setting the result display area of ​​the aging equipment in the visualization area, setting the bad sound and light alarm for the aging test, and setting the single point temperature over-temperature of the aging equipment. In addition, the system parameter setting window allows you to process test data for the drive motor controller to obtain model parameters. By collecting data from the drive motor controller, you can obtain corresponding basic information, temperature parameters, timing parameters, etc. Finally, the configured product parameters and model parameters are used as aging simulation parameters, and then aging simulation is performed on the drive motor controller based on the aging simulation parameters.

[0083] One of the above technical solutions has the following advantages or beneficial effects: the embodiment of the present application can flexibly configure the parameters by configuring the aging simulation parameters, thereby improving the intelligence of the system and providing a data basis for subsequent aging simulation.

[0084] In some embodiments, performing aging equipment setting processing on the drive motor controller based on the system parameter setting window to obtain product parameters includes the following steps:

[0085] In response to an operation instruction on the system parameter setting window, performing display area setting processing on the aging device of the drive motor controller through a collection editor to obtain area setting parameters;

[0086] In response to an operation instruction on the system parameter setting window, setting the device parameters of the burn-in device to obtain the burn-in device parameters;

[0087] In response to an operation instruction on the system parameter setting window, the burn-in device is connected to the manufacturing execution system to obtain system upload parameters;

[0088] The product parameters are obtained according to the regional setting parameters, the aging equipment parameters and the system upload parameters.

[0089] In an embodiment of the present application, in response to an operation instruction on the system parameter setting window, the operation instruction may be a keyboard or voice input operation, or may be an operation through mouse clicking, dragging, or the like, or a touch operation obtained through a touch screen, etc. In an embodiment of the present application, the display area setting process of the aging device of the drive motor controller is performed through a collection editor, specifically by clicking the button behind the area setting of the system parameter setting window. The form of the button can be set according to actual conditions, and the area and timing naming of the aging device are set according to the click instruction. Among them, the aging device can be an aging cabinet, an aging warehouse, or the like for performing aging tests on the drive motor controller. In a feasible embodiment, by configuring the area naming of the aging cabinet, and naming multiple timings of the designated area of ​​the aging cabinet, setting the row number allocation and column number allocation of the visualization area in the main interface, the position barcode rules of the multiple timings of the designated area of ​​the aging cabinet can also be set. It should be noted that the embodiment of the present application sets up multiple display areas in the visualization area of ​​the main interface. The aging results can be displayed in the corresponding display areas by reading the area setting parameters. For example, by reading the number of rows and columns configured for the aging cabinet, the display area can be positioned corresponding to the number of rows and columns in the visualization area, and the aging results of the aging cabinet can be displayed in the display area.

[0090] The embodiments of the present application can also configure and process the device parameters of the aging equipment to obtain aging equipment parameters. The aging equipment parameters include product specification configuration, product data collection configuration, product data refresh configuration, product data storage configuration, product compensation alarm configuration, temperature setting, water cooling setting, module configuration, etc. Among them, the product specification configuration is used to set the model parameter path required by the aging cabinet. The parameter path is a fixed path for product aging parameters, and a specific model can also be obtained through barcode scanning rules. The product data collection configuration is used by the aging equipment to determine whether the drive motor controller is in place. For example, a voltage sensor is set to collect the voltage of the voltage sensor as the voltage of the product test data. When the voltage data is the configured data, it is determined that the product is in place. The minimum current for determining whether the product is in place can also be set. When the current obtained is greater than the minimum current value, it indicates that the product is in place. The scanning position can also be set to determine whether the product is in place by scanning the position of the aging cabinet. The product data refresh configuration is used to refresh the drive motor controller. It can include a refresh interval and an automatic power-on wait delay. The refresh interval can be used to determine the product data and refresh the results to the visualization area of ​​the main interface after the load acquisition module communicates with the product to collect operating data. The automatic power-on delay is used to automatically start the aging operation after the self-test is completed and the delay time has passed. The product data storage configuration is used to save and set the message path and storage path. For example, by setting the ASC message path, the message storage path for the CAN data collected by the aging device is configured, and by setting the ASC file storage period, the ASC file storage time is configured. The product compensation alarm configuration is used to alarm and compensate for the number of abnormal inspections and product defects. For example, by configuring the number of abnormal product data inspections, if the number of inspections exceeds the set number, the product is determined to be abnormal and the data is set to 0 after normal. The embodiment of the present application can use the data refresh interval timing to determine whether the range of the collected data is within the parameter range set by the machine model parameters each time the set time is reached. If it is within the range, the data abnormality number is set to 0. When the data is abnormal, the data abnormality number is increased by 1. When the data abnormality number is greater than the product data abnormality inspection number, the product reports an abnormality and stores a record of the defect. The temperature setting is used to configure the temperature points of the product area and load area in the aging equipment, the electromagnetic lock unlocking temperature, the power-off temperature and other temperature parameters. Water cooling settings are used to configure the water temperature, water pressure, and filtration time in the aging equipment. Module configuration is used to configure the name, port, and communication of the hardware to be used.

[0091] The embodiment of the present application can also connect the aging equipment to the manufacturing execution system in response to the operation instructions in the system parameter setting window to obtain the system upload parameters. The system upload parameters are used to configure the upload parameters of the manufacturing execution system (MSE) and can be matched with the manufacturing execution system. By setting different parameter options, the entry and exit of the test product can be controlled. For example, after scanning the barcode, the interface is used to query the MES system whether the aging can be carried out. At the end of the aging, the test results are uploaded to the MES system through the interface. Finally, the set regional setting parameters, aging equipment parameters, and system upload parameters are combined to obtain the product parameters.

[0092] One of the above technical solutions has the following advantages or beneficial effects: the embodiment of the present application can configure the parameters of the aging device corresponding to the drive motor controller by setting the regional setting parameters, aging device parameters and system upload parameters, and obtain the corresponding product data through the aging device to set the aging parameters of the device. It can be applied to different test scenarios and can improve the flexibility of the system's aging test.

[0098] The machine model parameter is obtained according to the load parameter, the command parameter, the resolver parameter and the communication parameter.

[0099] In the embodiment of the present application, by operating the different buttons in the system parameter setting window, the load parameters, command parameters, resolver parameters, and communication parameters can be configured. The load parameters are used to set and process the output range and upper and lower load limits of the drive motor controller, and can configure the parameter specifications set and sampled on the device side. The command parameters are used to configure the product power on / off instructions, data read instructions, etc., for example, using data read instructions to sample and read data information from the drive motor controller. The resolver parameters are used to set the parameters of the resolver simulator, and the communication parameters are used to configure the LIN card as the instruction issued by the slave.

The operating conditions of the drive motor controller are monitored through the product parameters, specifically the drive motor controller is monitored through the parameter configuration of the aging equipment, and the working state of the driver on the vehicle can be simulated according to the operating conditions of the external equipment and the operating conditions of the controller, thereby performing aging simulation on the drive motor controller to obtain aging results. In a feasible embodiment, the controller temperature, drive waveform, and radiator temperature rise data can be collected in real time, and the signal distortion rate under high temperature can be recorded. The drive motor controller can also be tested for aging by monitoring the CAN bus message and detecting the temperature protection threshold trigger frequency. The vehicle climbing condition can also be simulated in the high temperature stage, and the stalled state can be simulated in the low temperature stage to simulate the real vehicle working condition. The embodiment of the present application also sets up a corresponding temperature control process. By pre-setting the temperature parameters, the equipment circulation fan is started at the beginning of the test, the temperature control heating is started according to the temperature parameters, and constant temperature aging treatment is performed when the set temperature is reached. At this time, if the temperature is higher than the exhaust temperature, the exhaust control is started to lower the temperature until the set temperature is reached. When the aging temperature is lower than the set temperature, the temperature controller is started for heating treatment.

[0112] Performing output configuration processing on the drive motor controller according to the load parameter and the sampled data to obtain output data;

[0113] The resolver simulator is set according to the resolver parameters, and the output data is transmitted to the resolver simulator according to the communication parameters. The operation of the external device is simulated by the resolver simulator to obtain the operation condition of the external device.

[0114] In the embodiments of this application, model parameters include load parameters, command parameters, resolver parameters, and communication parameters. The command parameters can be used to set product power-on and power-off commands and data collection commands. The product power-on and power-off command parameters are used to set startup and shutdown parameters. Startup parameters are used to set parameters such as startup time, startup mode (such as soft start or direct start), startup voltage, and current. For example, for soft start mode, the startup time can be set to 5 seconds, with the startup voltage gradually increasing from 0 to the rated voltage. Shutdown parameters are used to set shutdown time and shutdown mode (such as normal shutdown or emergency shutdown). Emergency shutdown can be used to quickly stop the motor in the event of a fault. Data collection commands are used to set data collection for the drive motor controller. The data collection interval can be determined based on the motor's operating characteristics and subsequent processing requirements, such as once per second or every 100 milliseconds, and the type of data to be collected, such as motor current, voltage, speed, and temperature, can be specified.

[0115] In one feasible embodiment, the control terminal sends a startup command to the drive motor controller via a communication interface based on the set startup parameters. Upon receiving the command, the drive motor controller starts the motor according to the preset startup mode and parameters and provides startup status information to the control terminal. The control terminal monitors the startup process in real time and promptly issues a shutdown command if any abnormality occurs (such as excessive starting current). The control terminal sends data acquisition commands to the sensor via the communication interface based on the set acquisition frequency and content. The sensor transmits the collected motor data (such as current, voltage, and speed) to the control terminal. The control terminal performs preliminary processing on the collected data, such as filtering and calibration, to improve data accuracy. Load parameters, such as load torque and load power, are then obtained based on the load parameters. The load parameters are transmitted along with the sampled data to the drive motor controller for output configuration processing, resulting in output data. The resolver simulator is then configured using the preset resolver parameters. The output data is transmitted to the resolver simulator based on the communication parameters. The resolver simulator simulates the operating conditions of the external device to determine the device's operating conditions.

[0116] One of the above technical solutions has the following advantages or beneficial effects: the embodiment of the present application can simulate the external device of the drive motor controller through the machine model parameters, thereby improving the aging efficiency of the drive motor controller.

[0117] In some embodiments, visually displaying the aging result based on the visualization area includes the following steps:

[0118] determining a region setting parameter according to the aging simulation parameter;

[0119] Displaying the aging result in the visualization area according to the area setting parameters to obtain a visualization result;

[0120] In response to an operation instruction on the visualization area, the visualization result is output as a status display to obtain status data and an output curve.

[0121] In an embodiment of the present application, the aging simulation parameters can be used to obtain the region setting parameters. The region setting parameters can be used to display the aging results in the visualization area according to the number of rows and columns. In one feasible embodiment, the visualization area in the interface displays the product status of six time series, with a total of three aging bins, each of which has two product positions. This embodiment of the present application can also display the product status of multiple time series, with no limit on the number. The voltage and current acquisition module collects load terminal voltage and current data, and product data is collected via CAN communication. The presence of a product is determined by scanning a barcode. It is contemplated that the embodiment of the present application can use different colors to indicate the status of the product position in the visualization area. For example, white can indicate idle or no product (no barcode scanned); red can indicate a defective product (the collected load data or product data is not within the set range of the model parameters); light green can indicate a product is present and OK (the collected load data and product data are both within the set range of the model parameters); yellow can indicate a failure (the product failed during the aging process, but the scanned data is now normal); and dark green can indicate a qualified result (the collected load data and product data are both within the set range of the model parameters throughout the aging process, and the final result is qualified).

[0122] In some embodiments, in response to an operation instruction on the visualization area, outputting a status display of the visualization result to obtain status data and an output curve includes the following steps:

[0123] In response to an operation instruction on the visualization area, obtaining an indicated position;

[0124] Comparing the indicated position with the displayed position of the visualization result, and when the comparison result shows that the positions are the same, obtaining the status data of the corresponding aging area, and displaying the status data in a pop-up window;

[0125] Perform curve modeling processing on the state data to obtain the output curve and display it.

[0126] In response to an operation command on the visualization area, such as placing the mouse over it, the visualization results can be displayed and status data can be obtained. This status data represents the current operating status of the device, the current temperature (collected and set via the PLC), the model name, the remaining run time, the aging time (obtained through the model and UI timing control logic), the number of aged products, and the input voltage (high-voltage module input voltage is collected and controlled via CAN communication, and low-voltage module input is collected and controlled via RS232 communication). Clicking the status display outputs the test parameters of the aging run: run time, start time, temperature, aging position, etc. Clicking the output button also displays an output curve, which can include a timing curve, temperature, water cooling temperature, water cooling flow rate, water cooling pressure parameters, and other curves to display the results.

[0127] One of the above technical solutions has the following advantages or beneficial effects: the embodiment of the present application displays the aging results through visualization, thereby improving the intelligence of the system and the user experience.

This embodiment utilizes a human-machine interface for interactive operation, where self-test burn-in, start burn-in, pause burn-in, and continue burn-in are displayed as time segments on a unified button. When the device is idle, the self-test burn-in display appears. After installing the product, loading the model, and scanning the barcode, click "Self-test burn-in" to enter the startup scan state. During this time, the current product status is refreshed, but no data is recorded. The button then changes to "Start burn-in." After the startup scan state refreshes the data and all is normal, click "Start burn-in" and select "Yes." Burn-in begins, and the button changes to "Pause burn-in." Select "No" to stop the self-test, turn off the input and load, and the button changes to "Self-test burn-in." When clicking "Pause burn-in" during burn-in, the button changes to "Continue burn-in." Click "Continue burn-in" and select "Yes" to continue the current burn-in process. The button changes to "Pause burn-in." Select "No" and follow the prompt to decide whether to stop. If "Yes," the "Stop burn-in" button changes to "Self-test burn-in." If "No," the button remains unchanged. After burn-in is complete, the button changes to "Self-test burn-in." This embodiment of the present application enters the model parameter interface, where the corresponding model parameters can be edited according to the specification. On the burn-in screen, click Select Model. A model selection field will pop up. Follow the prompts to select the burn-in model. Once the model is selected, the parameter name of the currently selected model will be displayed in the Model Name box in the Test Operation area. Place the test product in the corresponding position and enter the corresponding barcode. After connecting the product's inputs and outputs, click the Burn-in button to first power on the product, then scan it and determine if it is functioning properly. A normal display will be green, while a defective display will be red. If any abnormality is detected, click the Start Burn-in button and select the No button to terminate the input.
